Hello diyaudio.com community,
I purchased a kit from chipamp.com recently and I want to start building the enclosure while the packet is traveling around the world.
Can someone tell me the size of the fully populated amplifier pcb? And does someone know which height it has when it's populated?
Thanks in advance,
~Flo

Don't.
Wait until you have the whole chipamp working with it's PSU and other parts. Then work out how to package the complete amplifier. Then buy the size you need.

The thing is I want to make a gift for a friend and I am in kind of a hurry, so I planned everything ahead.
I did similar last year.
Planned as an Xmas present. Apologised gave alternative and delayed till Feb Birthday. Delayed and apologised again. Finally delivered April.
She loves it, but it took a lot longer than I planned.
My usual time line when in industry. Guess how long it will take and double it.
Eventually everyone learns I take twice as long as that doubled estimate.
I still work to that rule, think of a time and quadruple it.

I agree with Jim....
So many times I have built a Chassis then have something unexpected come up in the building of the circuit that causes me to have to change the dimentions or layout of my chassis which in the end causes the project to take longer and cost more money than it should ......

Allow for the intrusions created by the chassis hardware.
Allow for the transformer.
Allow for the PSU (rectifier and smoothing).
Allow for cable connectors.
Allow for the heatsink/s
Allow for the amp PCB/s, the decoupling electrolytics are likely to be the tallest item.
Note that the amp PCBs are only a small part of the whole contents.

He should know the size , it is sitting right in front of him ......
How? I can't find any dimensional drawings... except for the LM3886 itself.
